“Improving Reliability of Transmission Line Protection through Proper Setting, Testing, and Validation of Protection Systems”

This seminar will demonstrate why it is very important to have the correct system modeling data and how engineering estimates of that data can impact system reliability. Actual measured values are often critical for correct protection settings and the CP CU1 illustrates this by our example Case Studies. The vulnerability of the line protection coordination and operations are demonstrated using the estimated model data versus measured values data with RelaySimTest. System Testing proves the overall security of the protection scheme when correct settings are utilized.

Syllabus

Between 80-90% of all power system faults involve ground. Many protective relaying schemes depend on ground distance protection to accurately sense and locate ground faults on multi-terminal HV transmission lines. In addition to the need for dependable ground fault detection, protective relaying schemes must provide adequate selectivity and security to avoid overreaching and tripping for faults outside of its zone of protection or under reaching and not tripping when needed. These and other undesired consequences of such lack of scheme coordination have been a contributing catalyst of past system blackouts.

This seminar is intended to demonstrate that theoretical modeling of the HV grid alone is not adequate for proper engineering of the protection settings required to ensure the correct operation and protection of today’s high voltage transmission lines which are so critical for a reliable bulk delivery system. Today’s utilities and grid operators are mandated to provide a stable, safe, and reliable HV grid system. In order to do this utilities should leverage every tool and method available to obtain the correct system data and improve the security of their HV Line Protection Schemes and overall grid operations.

Using a combination of test methods and equipment we will demonstrate how the correct parameters can be obtained simply and efficiently. And when this data is applied using proper simulation tools prove the correct operations and coordination of the HV Line Protection Schemes  

Two case studies will be used to illustrate the advantages and time savings of direct measurements for obtaining the required line data and other parameters along with using modern system testing techniques with available grid simulation models. Relays and protection systems can be properly vetted both in the lab and in the field to ensure they are engineered for secure and reliable performance.
